The Mitas Ultra Heavy Duty 4 mm tube is engineered for the toughest conditions and for riders who refuse to compromise on protection. With its massive 4 mm wall thickness, this tube offers exceptional defense against pinch flats, making it the top choice for aggressive offroad terrain, rocky tracks, and high-impact enduro riding. When running low tire pressures for maximum traction, this tube provides a crucial buffer that absorbs hard hits and prevents snakebites.
For serious adventure and rally riders, this is the most robust option available in the Mitas lineup. The reinforced construction handles the brutal forces of fast, technical terrain and gives you the confidence to push harder without fear of damaging your tube. It is specifically designed for environments where the risk of puncture is high and reliability is non-negotiable.
On rough trails, in rocky desert stages, or during extreme enduro sections, the Ultra Heavy Duty tube stands out for its ability to withstand heavy impacts. Although it is heavier and can retain more heat than thinner tubes, its unparalleled protection makes it essential equipment for the most demanding riders and conditions.
Choose the Mitas Ultra Heavy Duty 4 mm tube when only maximum durability and confidence will do.
